I had a text doc in an USB with what I had copied in and thought was the passphrase I used for Qtum core. When i went to unlock it said it was invalid.
up
a couple scenarios:

1.) I ended up changing the passphrase and the words, but forgot to save the text doc before exiting.

2.) The text doc/usb were compromised and the password I had saved was used by a potential hacker to change the passphrase for the wallet so i can no longer access it.

Either way, I understand the carelessness and not writing down the passphrase on paper but need to find a way to get back in. There must be something I can do or a qtum team member I can talk to that can help.
